Abstract: The invention concerns exchanges switching telephone traffic, and in particular digital exchanges which have tie-lines passing therethrough. The exchange comprises control units (UC) and terminal units (UT) which are microprocessor controlled and which are connected to a switching network (RCX) by two-way multiplex links (MU). Some of the terminal units are connected to handle respective PCM junctions. At least one of the terminal units is a mixer and separator unit (UTB) which receives the signalling channels and in particular the signalling channels associated with the tie lines. This mixer and separator unit serves to forward signalling channel information for the tie lines. The terminal units connected to PCM junctions which include tie lines send the tie line signalling to the mixer and separator terminal unit, and also receive said signalling from said mixer and separator unit for onward transmission over a destination PCM junction.

Abstract: The device uses a supplementary microcomputer (P2) similar to a main control microcomputer (P1), to avoid excessive load control. The supplementary microcomputer (P2) is connected to the same device for detection of a control condition (Mer) so as to determine with the help of a prerecorded control law a simulated control (CF) of the load. The simulated control is transmitted to a calculating unit (SIM) to determine the effect of the simulation. A comparator (CMP) compares the effect (Eff) of the simulation with a real effect measurement (RE) on the load. The output (Coh) of the comparator (CMP) is connected to a generator circuit (INI) which orders an inhibit (Pe2) of the control command if the comparison is not coherent. ADVANTAGE - Avoids excessive control movement by simulating effect of control operation and comparing it with real-time control operation, with control inhibition being carried out if comparison is not acceptable.
